MUSTANG NERO is not really a hotel in the traditional sense, no reception desk, no bell boys, no bar, no room service. It's really an idiosyncratic guesthouse with quirky decor & people that try hard to do there best. The building was in an old office complex & the room reflected this. The room was large & had a moody, grey colour with exposed brutalist metal beams not seen in the posted photos. I looked at some of the other rooms and some had more cheerful colours than the room I stayed in. The downstairs area was the same grey colour as the room I stayed in. The animal theme was contained throughout the rooms and continued in all the common areas. Breakfast was great and the staff accommodated our food wishes. We did not linger too long in the common area, people were busy taking photos of the food and selfies with the animals & interiors. Hot water in bathroom was very reliable and owner went of her way to help with general information re Bangkok shops/curios. The area is out of the way of Bangkok sights. It's near BTS E8 & you have to travel outside to find reasonable coffee (e.g. Thong Lo) & travel afar to hip/trendy places to eat. Perhaps in a few years time the area will change. I notice Hof Art Gallery is nearby. It's a quirky place, suited maybe to groups travelling together.
